If Sean won by a ratio of 5:3, he'd get 5/(5+3), or 5/8th of the votes. 5/8ths of 120,000 is 5*15,000, or 75,000. John would get the remainder, which is 45,000.

S/J = 5/3
S + J = 120,000
--------------------
5 + 3 = 8
So,
S/5 = 120,000/8
S = (120,000 x 5) : 8
S = 75,000
J/3 = 120,000/8
J = (120,000 x 3) : 8
J = 45,000
Answer: The number of votes cast for John was 45,000.

3/8 x 120000= 45000 john
